v port 3i" and conn ports,` only one of Wl'iieh S l l0, one of said eirhaii )erts be i; between vpair olf cyliii-ilers 2G, 1

piston in cylinder, 'when the saiil pis t .i 1s at 'the end of its sti-olie away 'trein the head of the cylinder. The ports 'Til nonstitute the exhaust ports tor the cylinc and the exhaust ports of the cylinders 20, 2l, are connected Witt the exhaust pipe l'il and the exhaust ports ot the eylinilers 22, Y t are connected with the exhaust pipe (Si. 'the body portion of cach c liniler turther provided, in the iii-esentinstance, with one or more ports 72. which are locatedl below the exhaust ports it), so that they are eloseil by the piston in the cylinder when tlie exhaust port 7G is uncoiferctl by vthe piston. 'lhe ports 72 admit air into the crank ease 24, and this air is designed tobe :.iiliiiitteilinte the cylinder above the piston l ei'ein, through a pipo 74V-, which is eonnecteil at one end with the crank caso and at its other end with the interior ol the valve easing; 234 ln the present instance, the valve eiisii inovitled with tivo ollset pi'irtioiis i (see Fig. l), iii'hicli are aiifiin;l be located between the tiro pairs Cot evl'i ders and co'ipei'iite with i sages Ll2 ot the rotary valve.

rlfhe operation the nioloi herein may be eleii lv understood by liilleii' I. Working` of the rota" valve ii'illi ilu-inert to :i single erijlinilei, as tor instaure the Cylinder 20.

Referring to beginning ol ils suctif tary valve 2f) is about i e gras port 255 of the eyliiiiler 2O as riuiiiisei'tefl in Fig. 5, so that :is the piston iiioif'iis` (loira iii the cylinder l0 aiiil the ."zli'e x'eivzitiil in the cliicei'iioii of the arrow Si),

fresh ,ons il'xroiii the carburetor is (l through the hollow rotar-i' valve :inil ehr i the ports l?, 25 into the eylini'ler abo-re t piston 50. 'lhe rotation olf the valve 2? is timed with relation to the .sire the piston so as io lose the inlet poi-l 2o to the Cylinder sitter the piston has uiieoif the exhaust ports TO. Un the return er coni pres ion stroke oi the piston 30, the 'l'resli gas coiiiuesseil as, the poi-t 25, is closiril bythe rotary valve, as shown in itin'. il. 'the renin il as J lien tirait by the;

the piston is clriven fio'ivn again until. it anco1A irs the exhaust ports 70, and at or about the tinie the exhaust ports are unirerli on the explosion stroke of the pisi, the e ternal passage 42 of 'the rotary valve registers with the inouth of the aireliiiiiiher and with the gas inlet port 25 et the cylinder, whereupon fresh air under compression is oi'eeil from the crank case 24's through the pipe 74 into the chamber 7.5, thence through the external passage 42 and through the gas inlet port 25 into the cylini/ler as represented in ltig. 7. The fresh air rushes clown into the cylinder and sCavenges the same as it drives all of the burnt or iiaste gases out through the exhaust ports if() :incl the exhaust pipe v63, saidL ports and pipe being made large enough to insure all et the gases being driven from the cyliniler, thereby leaving only pure or fresh air in the cylinder, Which is expelled therefrom on the second upward stroke of the piston or what corresponds to the exhaust stroke of the ordinary four cycle motor. At or about the time the piston begins its second upward stroke, the external passage Ll2 in the .i'otary valve 2S) uncovers the auxiliary exhaust port (3G and Connects the cylinder 2O iibiive the piston with said auxiliary exhaust. 0n the second upstroke of the piston, the i'esli iiir filling the cylinclerlabove the pisioii is 'tori-eil out through the inlet port 25, theiiee through the passage 42 and through the auxiliary exhaust pipe Gl into the main :gli: list pipe i323. it or about the time the piston reaches the end of its second upstrolre, Ythe rotary valve cuts oit co1nrnuniration lietii'een the cylinder 20 and the auX- iliary exhaust (SO anil opens the port 25, thereby ioiii'ieetingg the cylinder with `the iiii.

crior ot the hollow rotary valve through the noi-m25, The movements of the piston iin-il rotary valve above described are then repeated. On each upstroke or" the piston, the air inlet ports 72 in the cylinder :ii'e uneoifered, and air -is admitted into the linilcr belowv the piston. 'll his air is then :terreil iloii'n into the crank case on the Clown stroke oit the piston and compressed therein, anfl il e :iir iiufler more or less pressureiu, the erzielt ease passes through the pipe Tl, eierniil passage in the rotary valve, t" uit-ih the port 25 and into the cylinder above the piston. rlhis air carries with it iiiore or less oil from the crank ease, and bolli to cool the rotary valve and the cylinder at its hottest part, and further the. oil serves to assist in lubricating the rotary valve :inil the reciprocating piston. Furierinore this cooling,` elect is augmented by o the auxiliary exhaust pipe 62.

tl the :iir on its passage up out of the Cylinder tl will be observed, that all of the burntl i or het are driven out oit. Athe cylinder' through the, main e by the lesh zur a ,i termal pai.
